Hello,

 A group within our Physics department have a 5 Tesla solenoid for testing
properties of magnetic materials. The machine is controlled via serial cables
driven by a SE30 and HyperCard. It is required that the Mac be close to the
machine for the operator to see what is happening. When the field is at 5T
nearby colour monitors are visibly distorted and the SE's screen is just
starting to distort.

 The group are about to take delivery of a 12T solenoid, so my question is : 

   Will a hard disk on SE30 start losing data in this field ?
